Grub's SuperSport 8.5 MID Cut Boot - Men's & Women's

The New Grub's SuperSport 8.5 has 8.5mm of insulation rated to
-40Â°F that has been tested to extremes in the tundra of Siberia. The
combination of fleece, highloft, and 8.5mm of CR-Foam traps warm air
against the foot and moves sweat away from the foot. Vibram's excellent
multi-sport sole and EVA midsole gives this boot superior grip on all
surfaces.
